Power bank is good enough at this price...i used this product for 5-6 days1.It takes 9 hour for full charging from 0 level....2.It didn't heat like others....3.Colour is decent...3.4 led blue light which indicate level of charging...4.2 port are there for charging...5.Delivered after 1 day...6.Box also contain 1 small black usb....i am satisfied with this product...thanks flipkart....

charging time is little bit more and it's efficiency is much good. I will prefer not to use any power bank, most of powerbanks diminish the battery life of mobile phone. it should be only for emergency use.
